welcome to the listing
plug and play (no soldering or resistors required) Auto bed leveling Sensor with 8mm** sensing distance for Anet v1.0 main board 3d printers- these include the Anet A8, A6 and A2 3d printers
they will require a firmware update to enable auto bed leveling which i recommend SKYNET3D-V2
this is an LJ18A3-8-Z/BX sensor with jst plug already installed and tested before i post them out.. the 8mm sensing distance allows you to still have your chosen build surface such as build tak ,kapton , or glass(3mm).
i suggest heading over to http://www.facebook.com/skynet3ddevelopment to get the firmware required and information on how to install and configure your sensor.
items will be posted by royal mail once ive received payment in full
happy printing
** actual sensing distance will be reduced if you are using an aluminium bed on your 3d printer based on the information below taken from this website:

Target Correction Factors for Inductive Proximity Sensors
To determine the sensing distance for materials other than the standard mild steel, a correction factor is used. The composition of the target has a large effect on sensing distance of inductive proximity sensors. If a target constructed from one of the materials listed is used, multiply the nominal sensing distance by the correction factor listed in order to determine the nominal sensing distance for that target. Note that ferrous‐selective sensors will not detect brass, aluminum or copper, while nonferrous selective sensors will not detect steel or ferrous‐type stainless steels.
The correction factors listed below can be used as a general guideline. Common materials and their specific correction factors are listed on each product specification page.
(Nominal Sensing Range) x (Correction Factor) = Sensing Range. | Correction Factors |
| Target Material | Approximate Correction Factor |
| Mild Steel | 1.0 |
| Stainless Steel | 0.85 |
| Brass | 0.50 |
| Aluminum | 0.45 |
| Copper | 0.40 |

The size and shape of the target may also affect the sensing distance. The following should be used as a general guideline when correcting for the size and shape of a target:
- Flat targets are preferable
- Rounded targets may reduce the sensing distance
- Nonferrous materials usually reduce the sensing distance for all‐metal sensing models
- Targets smaller than the sensing face typically reduce the sensing distance
- Targets larger than the sensing face may increase the sensing distance
- Foils may increase the sensing distance
